Import Data SSAS Memory issue

Hey everyone 🙂

I'm trying to build my reports using SSAS and since i'm very limited with live connection i figured I would try the Import Data option. I imported my dimension tables, but I have a memory issue when I try to upload a view which has around 4M rows. I get this error:

I have installed the 64bit version. Is it because of its size that I can't upload it? And if so, is there any limitation of the size when using Import Data on SSAS.

Thanks 🙂

I was getting the same issue and after troubleshooting a bit I realized what the import was doing. When you select multiple tables, PowerBI seems to do a cross join on those tables. This leads to a huge data explosion and that is why the server runs out of memory. Try importing only one table at a time.

I had the same problem. Your comment solved my problem. Thank you!

Hi @Anonymous,

Power BI Desktop uses much RAM when working on it. When importing large data source with huge number of rows,  you will get the above error if the memory is not sufficient. In your scenario, please increaser your RAM and use 64 bit Power BI Desktop to import SSAS data.

In addition, it doesn’t mention any size limitations when connecting to SSAS Multidimensional Models in Power BI Desktop in this article,  however, there are other limitations, for example, servers must be running SQL Server 2012 SP1 CU4 or later versions of Analysis Services, please take a look at the “Limitations of SSAS Multidimensional Models in Power BI Desktop” part to get more details.

Hey @v-yuezhe-msft

You mentioned above "...servers must be running SQL Server 2012 SP1 CU4 or later versions of Analysis Services...."

Where can I check If my server is running this version of Analysis Services? 

Thanks

Hi @Anonymous,

Please follow the instructions in the blog below to determine SQL Server Analysis Services version.
